The following two papers describe such an event.In 1961, Drs. Mary Efron and Emily Bixby began a metabolic screening program of the 2,000 patients at the Wrentham State School. As part of this, in order to assess the frequency of homocystinuria, they performed the cyanide-nitroprusside test on urine samples of all the patients. Five tests were positive.

However, the fifth patient proved to be of even greater interest since here the positive nitroprusside reaction was due to a new sulfur-containing amino acid which, as it |
